To all whom it may concern:

Be it known that I, HENRY JACOB, citizen ofthe United States, residing at lNew Orleans, in the parish of Orleans and State of Louisiana, have invented newand useful Imof the can being readily placed kin position precedent tosaid operation andy as'readily removed subsequently to the'same.

With the foregoing in view the invention will be fully understood fromthe' following description and claims when thesameare read in connection with the drawings, accompanying and forming part of this Ispecification, in which:

VFigure lis a side elevation of a can seamlng machine embodying my improvements.

Fig. 2 is an enlarged front elevation ofthe same. Fig. 3 is a detail, enlar ed section illustrative of the manner in whic the seaming roller or roller die is mounted 'on'the swinging support by which it is carried.

. Similar letters and numerals designate correspondingparts in all of the views of the drawings, referring to which:`

IA is the main frame of the machine which may be of vany construction consonant with Y the purpose `of my invention.'r B` is a longitudinally disposed, drive-shaft journaled in said main frame and equipped, by preference, with'fast'and loose band pulleys, and also preferably provided with aV male lroller die C of a combined beading and mouthing set of dies. y

D is a stop adjustably fixed to the main frame and having for its office to limit rearward movement of the can'.

E is a vertically swinging frame', hinged at' 3 to the main frame; Y

F is a s ring connected to asupport 4 on s is a longitudinallydisposed shaftjour-l naled in andmovable vertically with the swinging frame E and having a spur gear 6 designed to be intermeshed with'- a corresponding gear 7 `on the shaft B, and carrying t e female roller dieH of the combined bead-` ing and mouthing set of dies, and also carry-` ing the swaging'roller Iof the seaming set.

For the purpose of enabling the machine attendant to draw and hold the frame E and shafts down, against the action of the spring F, I provide the said frame E with a crossbar Gr to which are connected depending rods Y J, Fig. 2, which, in turn, are designed to be connected with a treadle or the like (not shown).

Fixed to and reaching forwardly from the main frame A is a horizontal arm K, and on said arm is a fixed work-.support L and a slide-rest M, the latter of dovetail form in cross-section; Snugly fitting and adjustable on the said slide-rest Mis a body a which is designed 'to be adjustably fixed to the rest through the medium of set screws c andd. At this point I desire to state lthat I prefer to key or feather the swaging rcoller I of the l seaming set' on the shaft s so as to permit of the adjustment of said roller in the direction ofthe len th of the shaft, and that the purpose of a justably fixing the body a to the slide-restM is to permit of said body and the parts which it carries, as presently described, being adjusted lengthwise of the machine with the roller I in order to adapt the machineto operate on cans of various lengths.

Pivoted and arranged toswing horizontally on a vertical pin f carried by the body a is'the'end platev E3 comprised in my imrovements, which end plate-is designed to be conveniently swung outwardly and inwardly through the medium of a handle g fastened thereto through the medium of bolts g or other suitable means. The said end plate E3 is provided on its free or swinging end with a portion n, of hard steel, arranged when the plate is swung inwardly to the working osition illustrated, to be retained and held etween a stop pin h on the body a,

and a swinging latch i, pivoted aty' to the body and arranged to swing vertically. The said latchvi is normally held by a spring Z against a stop pin k on the `body a; and it is pressed by a s ring 'm against the side of the said body a. i v rom'this it follows that when the end plate E3 is swung inwardly to the position illustrated, itsportion n will ride over the latch 'L and be confined between the said latch in such manner that there is no liabilityv of saidendiplate being. casually released and permitted to swing outwardly during the operation of the machine. It will be understood,however, that when suflicient pull is exerted on the handle g, the portion n of the end plate E3 will depress the latcht and ride over the same, whereupon the plate may be swung open to the full extent. Connected through four, more or less, bolts F3 in an adjustable manner with the plate E3 is an auxiliary plate G', preferably of steel, which auxiliary plate corresponds in outline to the plate E3, with the exception that it is provided with a projecting tongue p designed to bear against the outer end of the can with a view of assisting` in retaining the same in proper position 11 is a bushing, preferably of tool steel, mounted in the upper portion of the plate E3. 12 is a. shaft extending through said `bushing and also extending through the aux- 'iliary plate G and provided on its forward or inner end and at the inner or forward side of they auxiliary plate with a seaming roller 14 adapted to cooperate with the swaging roller I on the shaft s.

13 13 are anti-friction balls arranged in a race formed between the forward end portion of the bushing 11 and the shaft 12.

15 is a collar mounted on the shaft 12 at a point in rear of the bushing l1. 16 16 are anti-friction balls arranged in a race between the bushing 11 and said collar 15, and 17 17 are nuts mounted on the rear portion of the shaft 12 and backing the said collar 15. By virtue of the. construction described it will be observed that when wear of the balls or their bearings takes place, such wear may be taken up by adjusting the nutsL 17 on the shaft 12 and adjusting the auxiliary plate G with respect to the plate E3.

In the operation of my improvements, the end of a can, after being shaped by a block or other means to provide it at its edge with a channel adapted to receive the end of a straight can body, is slipped on the end of the body, and then the can is placed against the stop D and on the two lower roller dies C and 14., the plate E3 being swung inwardly to the position shown in li'ig. 1 after the can is placed against the stop D and on the roller die C. The drive-shaft B is then rotated and the shaft s is drawn downward whereupon the two sets of rollers will be caused to simultaneously operate upon the can to seam the body to the bottom, produce a bead adjacent to` the mouth of the can and form a taper at the mouth for the reception of a slip cover (not shown). Incidental to the seaming of the bottom to the body it will be manifest that the. swagingv roller I will, through the medium. of the can, transmit rotary motion to the seaming roller 14. On the completion of the operation on the can, the shaft s is permitted to move upwardly under the action. of the spring F, and the, plate E3 is swung open, when, as will be readily understood, the can may be expeditiously and easily removed from the machine.

The construction herein illustrated and described constitutes Vthe best practical enibodiment of my invention of which I ain cognizant, but it is obvious that in the future practice of the invention such changes may be made as fairly fall within the scope of my invention as defined in the appended claims.

Having described my invention, what I claim and desire to secure by Letters-Pat ent, is:

1. In a machine for the purpose described, the combination of a main frame, a driveshaft, a driven shaft pivotally mounted over the drive-shaft, a driving connection between the two shafts, a horizontally swinging plate pivotally connected with the main frame at one side of the longitudinal vertical plane of the shafts, and a set of rollers, one roller of which is carried by the driven shaft and the other by the horizontally swinging plate.

2. In a machine for the purpose described, the combination of a main frame, a driveshaft, a driven shaft pivotally mounted over the drive-shaft, a driving connection be tween the two shafts, a horizontally swinging plate pivotally connected with the main frame at one side of the longitudinal vertical plane of the shafts, means for detachably securing said plate in a position at a right angle to the shafts, and a set of rollers, one roller of which is carried by the driven shaft and the other by the horizontally swinging plate.

3. In a machine for the purpose described, the combination of a main frame, a body adjustable on the main frame in the direction of the length of the machine, means for adjustably fixing the body to the main frame, a drive shaft, a driven shaft pivotally mounted over the drive-shaft, a driving connection between the two shafts, a combined beading and mouthing set of rollers one of which is mounted on the drive-shaft and. the other on the driven shaft, a horizontally swinging plate pivotally connected with the adjustable body, means on the body for detachably securing said plate in its workingr position at a right angle to the shafts, and a set of seaming rollers, one roller of which derives motion from the driven shaft and is adjustable on said shaft in the direction of the length thereof, and the other roller of which is carried by the swinging plate and movable into and out of its working position with said plate.

4. In a machine for the purpose described, the combination of a main frame, a drive shaft, a driven shaft pivotally mounted over the drive-shaft, a driving connection between the two shafts, a roller mounted on the driven shaft and forming one of a sealning set of rollers, a swinging plate connected With the main frame, means for detachably' securin said plate in its Working position,

an auXi iary plate adjustably connected with.
